   - Senpai (increased the note speed)
   - Thorns (increased the note speed slightly)
 - Favorite songs marked in Freeplay are now stored between sessions.
+- In the event that the game cannot load your save data, it will now perform a backup before clearing it, so that we can try to repair it in the future.
 - Custom note styles are now properly supported for songs; add new notestyles via JSON, then select it for use from the Chart Editor Metadata toolbox. (thanks Keoiki!)
 - Improved logic for NoteHitScriptEvents, allowing you to view the hit diff and modify whether a note hit is a combo break (thanks nebulazorua!)
 - Health icons now support a Winning frame without requiring a spritesheet, simply include a third frame in the icon file. (thanks gamerbross!)
